Ragdoll cats with pointed markings will turn black in winter, while those with other markings will not. The reason they turn black is due to a mutation in their TYR gene, which changes the tyrosine that controls their synthesis. This causes their skin to become darker and darker in cold weather.
This is why pointed Ragdoll cats have some darker areas than others. For example, their face and tail are darker due to the influence of tyrosinase, while other areas are not significantly affected. Moreover, they only become darker when the weather gets colder.
How to prevent Ragdoll cats from getting sick in winter
If your Ragdoll cat turns black, take precautions to keep it warm during winter. Feed it warm water and warm dog food, and keep the temperature around 27-29 degrees Celsius. Avoid feeding it raw or cold food. You can also turn on the heater to raise the indoor temperature and prevent it from turning black.
